The report,, reviews the effects of ocean warming on species, ecosystems and on the benefits oceans provide to humans. Compiled by 80 scientists from 12 countries, it highlights detectable scientific evidence of impacts on marine life, from microorganisms to mammals, which are likely to increase significantly even under a low emissions scenario.

“Ocean warming is one of this generation’s greatest hidden challenges – and one for which we are completely unprepared,” says��������ϲʿ�������ֳ�ֱ�� Director General Inger Andersen. “The only way to preserve the rich diversity of marine life, and to safeguard the protection and resources the ocean provides us with, is to cut greenhouse gas emissions rapidly and substantially.”

Ocean warming is already affecting ecosystems from polar to tropical regions, driving entire groups of species such as plankton, jellyfish, turtles and seabirds up to 10 degrees of latitude towards the poles, causing the loss of breeding grounds for turtles and seabirds, and affecting the breeding success of marine mammals, according to the report.

By damaging fish habitats and causing fish species to move to cooler waters, warming oceans are affecting fish stocks in some areas and are expected to lead to reduced catches in tropical regions, the report states.

In East Africa and the Western Indian Ocean, for example, ocean warming has reduced the abundance of some fish species by killing parts of the coral reefs they depend on, adding to losses caused by overfishing and destructive fishing techniques. In South-East Asia, harvests from marine fisheries are expected to fall by between 10% and 30% by 2050 relative to 1970-2000, as the distributions of fish species shift, under a high ‘business as usual’ greenhouse gas emission scenario, the report states.

“Most of the heat from human-induced warming since the 1970s – a staggering 93% – has been absorbed by the ocean, which acts as a buffer against climate change, but this comes at a price. We were astounded by the scale and extent of ocean warming effects on entire ecosystems made clear by this report,” says��Dan Laffoley, Marine Vice Chair of the World Commission on Protected Areas at ������ϲʿ�������ֳ�ֱ��, and one of the lead authors.

The report also highlights evidence that ocean warming is causing increased disease in plant and animal populations, and impacting human health as pathogens spread more easily in warmer waters, including cholera-bearing bacteria and harmful algal blooms that cause neurological diseases like ciguatera.

Warming oceans are also affecting the weather, with a range of knock-on effects on humans. The number of severe hurricanes has increased at a rate of around 25-30% per degree of global warming, the report states.

Ocean warming has led to increased rainfall in mid-latitudes and monsoon areas, and less rain in various sub-tropical regions. These changes will have impacts on crop yields in important food-producing regions such as North America and India, according to the report.

The protection against climate change offered to us by oceans and their ecosystems – such as absorbing large amounts of CO2 and sheltering us from storms and erosion – is also likely to reduce as the ocean warms, according to the report.

The report’s recommendations include recognising the severity of ocean warming impacts on ocean ecosystems and the benefits they provide to humans, expanding marine protected areas, introducing legal protection for the high seas, better evaluating the social and economic risks associated with warming oceans and continuing to fill gaps in scientific knowledge, as well as cutting greenhouse gas emissions rapidly and substantially.

Ocean conservation is one of the major themes addressed by the ongoing ������ϲʿ�������ֳ�ֱ�� Congress, where ������ϲʿ�������ֳ�ֱ�� Members will vote on motions related to����and����among many others.

XL Catlin, is the global brand used by XL Group Ltd’s (NYSE:XL) insurance and reinsurance companies. XL Catlin’s interest in ocean science research stems from its position as a leading insurer and reinsurer and its need to understand how the global risk landscape will change in the future. XL Catlin sponsored the Arctic Survey’s (2009 – 2011) that investigated the impacts of changes to the Arctic Ocean and the XL Catlin Seaview Survey (2012-present) that created the first digital baseline of coral reef health, which is freely available on the XL Catlin Global Reef Record.�� In 2016 XL Catlin is also supporting Nekton’s Science Research Programme, the XL Catlin Deep Ocean Survey, creating a new standardised methodology to be used by marine biologists for measuring physical, chemical and biological indicators to assess the function, health and resilience of the deep ocean.
